Detailed Description

[ description of embodiments of the present disclosure ]

Embodiments of the present disclosure are first listed for illustration.

The wiring member of the present disclosure is as follows.

(1) A wiring member includes: a wiring body including a sheet member and a linear transmission member fixed to the sheet member; and a shape maintaining member formed in a sheet shape having a higher rigidity than the sheet-like member, and covering at least one side in a front-back direction of the wiring body to maintain a shape of the wiring body. Thus, since the shape maintaining member having higher rigidity than the sheet-like member covers the wiring body, the wiring member is less likely to sag, and the ease of assembly of the wiring member can be improved.

(2) It is also possible to adopt a manner in which the shape maintaining member has a one-side covering portion that covers the linear conveyance member only from the side opposite to the sheet-like member. This can reduce the number of components compared to the case where the shape maintaining member covers both sides.

(3) In the one-side covering portion, the shape maintaining member and the sheet-like member may be directly fixed at a contact portion on a side of the linear transport member. Thus, the fixing member remaining on the wiring member for fixing the shape maintaining member and the sheet member can be omitted.

(4) It is also possible to adopt a manner in which the shape maintaining member has both side covering portions that cover both sides in the front-rear direction of the wiring body. Thus, the rigidity of the wiring member can be further improved by providing the both-side covering portions. Alternatively, since the necessary rigidity can be obtained by the shape maintaining members on both sides, a member having a small rigidity can be used as one shape maintaining member.

(5) The shape maintaining member may be provided continuously along the longitudinal direction of the wiring body so as to maintain the shape of the entire wiring body. This can improve the rigidity of the entire wiring member.

(6) It is also possible to adopt a manner in which the shape maintaining member is provided so that the wiring member can be folded at the intermediate portion. Thus, the wiring member is folded at the intermediate portion, and the configuration during conveyance can be made compact.

(7) Further, the wiring member of the present disclosure includes: a wiring body including a sheet member and a linear transmission member fixed to the sheet member; and a shape maintaining member formed in a sheet shape having a higher rigidity than the sheet-like member, and configured to cover at least a part of at least one of the front surface and the back surface of the wiring body to maintain the shape of the wiring body. Thus, since the shape maintaining member having higher rigidity than the sheet-like member covers the wiring body, the wiring member is less likely to sag, and the ease of assembly of the wiring member can be improved.

(8) The plurality of base materials of the sheet-like member may be arranged in series along a longitudinal direction of the linear transport member. This can improve the yield of the sheet-like member.

(9) The suction pad may be provided so as to be able to contact a position where the shape maintaining member is exposed when the wiring member is folded in the intermediate portion. This makes it easy to transport the wiring member in the folded state by a robot or the like.

(10) The sheet-like member and the shape-retaining member may be fixed to each other with an adhesive or a resin. This structure is preferable in terms of widening the range of choices of the shape maintaining member having a rigidity different from that of the sheet-like member.

(11) The sheet-like member and the shape maintaining member may be directly fixed at a contact portion. This structure does not require a different material to be interposed between the sheet-like member and the shape maintaining member, as compared with a structure in which the sheet-like member and the shape maintaining member are directly and indirectly fixed. Therefore, this structure is preferable from the viewpoint of cost reduction and the viewpoint of reduction in thickness of the wiring member itself.

(12) The shape maintaining members may be provided at intervals in the longitudinal direction of the wiring body, and the shape maintaining members provided at the intervals may be folded. This allows the wiring member to be folded with a simple structure.

(13) In the wiring body, the shape maintaining member may include a corrugated portion formed such that a ridge and a valley are continuous in a longitudinal direction of the wiring body, and the shape maintaining member may be foldable at a portion covered with the corrugated portion. Thereby, the shape maintaining member can cover the wiring body in such a manner that the wiring member can be folded.

(14) The shape maintaining member may be foldable so that the outward main surface of the shape maintaining member provided in the middle portion is exposed in a state where the end portion side portion is folded to be overlapped on the middle portion. This enables the suction pad to contact the shape maintaining member portion exposed at the middle side portion. This makes it easy to transport the wiring member in a folded state by a robot or the like.

(15) It is also possible to adopt a form in which the shape maintaining member includes: a planar forming part formed in a planar shape; and a three-dimensional forming part which is formed to stand from a part of the planar forming part along the width direction to the front and back direction of the planar forming part and extend along the long side direction. Thus, the rigidity of the shape maintaining member can be further improved by providing the three-dimensional forming portion.

(16) A plurality of the linear transmission members may be provided in parallel. This enables the wiring member to be formed flat.

[ details of embodiments of the present disclosure ]

Specific examples of the wiring member of the present disclosure will be described below with reference to the drawings. In addition, the present disclosure is not limited to these illustrations, but is shown by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

[ first embodiment ]

The wiring member according to the first embodiment will be described below. Fig. 1 is a plan view showing a wiring member 10 according to a first embodiment. In fig. 1, the left-side end portion shows a state before folding, and the right-side end portion shows a state after folding. When the right-side end portion is deployed, it is the same as the left-side end portion. Fig. 2 is a sectional view taken along line II-II of fig. 1. Fig. 3 is a sectional view taken along line III-III of fig. 1. Fig. 4 is a partial sectional view taken along line IV-IV of fig. 1. Fig. 5 is a schematic sectional view taken along line V-V of fig. 1.

The wiring member 10 is a member that is connected to a component mounted on a vehicle and transmits electricity and/or light to and/or from the component. The wiring member 10 includes a wiring body 20 and a shape maintaining member 40 attached to the wiring body 20. In the wiring member 10, the shape of the wiring body 20 is maintained by the shape maintaining member 40. For example, the shape of the wiring body 20 is preferably maintained in a state of being disposed on a vehicle or in a state of being close to the vehicle. Thereby, when assembling the wiring member 10 to the vehicle, the trouble of arranging the wiring bodies 20 can be omitted.

The wiring body 20 includes a sheet member 22 and a linear transmission member 30 fixed to the sheet member 22. Here, a plurality of linear transmission members 30 are fixed to the sheet member 22. Thereby, the plurality of linear transmission members 30 are positioned to each other.

The sheet member 22 is used for fixing the linear transport member 30. The material constituting the sheet-like member 22 is not particularly limited, and may be, for example, a material containing a resin such as PVC (polyvinyl chloride), PE (polyethylene), PET (polyethylene terephthalate), PP (polypropylene), and PA (polyamide), or a material containing a metal such as aluminum or copper. The structure of the sheet-like member 22 is not particularly limited, and may be a fibrous material having fibers such as a woven fabric, a knitted fabric, or a nonwoven fabric, or a non-fibrous material having no fibers such as a member obtained by extrusion molding, injection molding, or the like. When the sheet-like member 22 is a non-fibrous material obtained by extrusion molding, injection molding, or the like, it may be a foamed material subjected to foam molding or a filled material uniformly filled without foam molding. Preferably, the sheet member 22 is formed to have flexibility.

Further, the sheet member 22 may have only one layer or may have a plurality of layers. In the case where the sheet member 22 has a plurality of layers, the material, structure, and the like of each layer can be appropriately set. For example, the sheet-like member 22 may be a member in which a resin layer and a resin layer are stacked, a member in which a resin layer and a metal layer are stacked, or a member in which a metal layer and a metal layer are stacked. The sheet-like member 22 may be a member in which a non-fibrous material layer and a non-fibrous material layer are stacked, a member in which a non-fibrous material layer and a fibrous material layer are stacked, or a member in which a fibrous material layer and a fibrous material layer are stacked.

Here, the sheet-like member 22 is formed in a shape corresponding to the path of the linear transport member 30 (H-shaped in a plan view in the example shown in fig. 1). In this case, the sheet member 22 may be constituted by one base material or a plurality of base materials connected to each other. When a plurality of substrates are connected, the substrates may have a shape with a high yield, such as a square shape.

Here, the width dimension of the sheet-like member 22 (the dimension of the sheet-like member 22 along the direction in which the linear conveyance members 30 are arranged) is the same at each position, but may be different depending on the number, thickness, and the like of the linear conveyance members 30. For example, when the size of the linear conveyance member 30 along the parallel direction changes, such as before and after branching, the sheet member 22 on the side where the size of the linear conveyance member 30 along the parallel direction is larger is considered to have a larger width than the sheet member 22 on the side where the size of the linear conveyance member 30 along the parallel direction is smaller.

The linear transmission member 30 may be a linear member that transmits electricity, light, or the like. For example, the linear transmission member 30 may be a general electric wire having a core wire and a coating layer around the core wire, or may be a bare wire, a shielded wire, an enameled wire, a nichrome wire, an optical fiber, or the like.

The linear transmission member 30 for transmitting power may be various signal lines and various power lines. The linear transmission member 30 that transmits electricity can be used as an antenna, a coil, or the like that transmits or receives signals or power to/from a space.

The linear transmission member 30 is considered to include a transmission line main body 32 that transmits electricity or light and a clad layer 34 that covers the transmission line main body 32. For example, in the case where the wire-shaped transmission member 30 is a normal electric wire, the transmission line main body 32 corresponds to a core wire, and the coating layer 34 corresponds to an insulating coating layer. The core comprises one or more single wires. The element wire is formed of a conductive material such as copper, copper alloy, aluminum alloy, or the like. When the core wire is formed of a plurality of element wires, the plurality of element wires are preferably twisted. The insulating coating layer is formed by extrusion molding of a resin material such as PVC or PE around the core wire.

In the example shown in fig. 1, each end of the linear transmission member 30 is connected to a connector C. The connector C is connected to a mating connector provided on a component mounted on the vehicle, a mating connector provided on an end portion of the linear transmission member 30 extending from the component mounted on the vehicle, or the like. However, the end of the linear transport member 30 may be connected to the connection object without the connector C.

The number of the linear transmission members 30 may be one or a plurality of them, and may be set as appropriate according to the number of circuits of the wiring member 10 and the like. When a plurality of linear transmission members 30 are provided, the linear transmission members 30 may be bundled or may be arranged in parallel on the sheet member 22. In the example shown in fig. 1, a plurality of linear conveyance members 30 are juxtaposed on the sheet-like member 22.

When a plurality of linear transmission members 30 are provided, the diameter, the use, the shape, and the like of each linear transmission member 30 may be appropriately set.

In the example shown in fig. 1, a plurality of linear conveyance members 30 extend parallel to each other on the sheet-like member 22, but this is not a necessary structure. For example, the plurality of linear transmission members 30 may intersect with each other. In the example shown in fig. 1, the linear transmission member 30 is disposed in a curved manner on the sheet-like member 22. In particular, in the example shown in fig. 1, the sheet member 22 is branched. However, it is not essential to form branches on the sheet-like member 22 and to bend the linear transport member 30 on the sheet-like member 22, and the path of the linear transport member 30 on the sheet-like member 22 can be set as appropriate.

In the example shown in fig. 1, the linear transmission member 30 has a middle portion fixed to the sheet-like member 22 and end portions extending to the outside of the sheet-like member 22, but this is not necessarily required. The end of the linear transport member 30 may be located on the sheet-like member 22.

The linear transmission member 30 is fixed to the sheet member 22. The fixing manner of the sheet member 22 and the linear transport member 30 will be described in detail later.

The shape maintaining member 40 is formed in a sheet shape having higher rigidity than the sheet-like member 22. The shape maintaining member 40 may be any member having higher rigidity than the sheet-like member 22, and the material, structure, and the like of the shape maintaining member 40 are not particularly limited. The material may be, for example, a material containing a resin such as PVC, PE, PET, PP, and PA, or a material containing a metal such as aluminum or copper. The structure may be a fibrous material having fibers such as a woven fabric, a knitted fabric, or a nonwoven fabric, or may be a non-fibrous material having no fibers such as a member obtained by extrusion molding or injection molding. When the shape maintaining member 40 is a non-fibrous material obtained by extrusion molding, injection molding, or the like, it may be a foamed material subjected to foam molding or a solid material uniformly filled without foam molding. Here, a case where the shape maintaining member 40 is a non-fibrous material made of nylon, PP, or the like will be described.

The shape maintaining member 40 may have only one layer or may have a plurality of layers. When the shape maintaining member 40 has a plurality of layers, the material, structure, and the like of each layer can be appropriately set. For example, the shape maintaining member 40 may be a member in which a resin layer and a resin layer are stacked, a member in which a resin layer and a metal layer are stacked, or a member in which a metal layer and a metal layer are stacked. The shape maintaining member 40 may be a member in which a non-fiber material layer and a non-fiber material layer are stacked, a member in which a non-fiber material layer and a fiber material layer are stacked, or a member in which a fiber material layer and a fiber material layer are stacked.

The shape maintaining member 40 covers at least one side in the front-back direction of the wiring body 20 to maintain the shape of the wiring body 20. Here, the wiring member 10 has a one-side covering portion 12. The one-side covering section 12 is a section where the shape maintaining member 40 covers the linear transport member 30 only from the side opposite to the sheet member 22. In the example shown in fig. 1, a case where only the one-side covering portion 12 is provided will be described. Therefore, here, the shape maintaining member 40 covers only one side of the wiring body 20 in the front-rear direction.

The shape maintaining member 40 may be configured to cover the entire area of the sheet member 22 along the path of the linear transport member 30, or may be configured to cover only a portion thereof. Here, the shape maintaining member 40 covers most of the entire area along the path of the linear transport member 30 except for a part of the area. At this time, the region along the path of the linear transport member 30 where the sheet-like member 22 is not covered with the shape maintaining member 40 may be an end portion of the sheet-like member 22 or an intermediate portion. In the example shown in fig. 1, a region where the sheet-like member 22 is not covered with the shape maintaining member 40 exists in the middle portion of the sheet-like member 22 along the path of the linear conveyance member 30. This region is the region for folding.

The portion continuously covered with the shape maintaining member 40 may be constituted by one base material, or may be constituted by a plurality of base materials connected to each other. When a plurality of substrates are connected, the substrates may have a shape with a high yield, such as a square shape.

Here, the width dimension (dimension along the direction in which the linear conveyance members 30 are arranged) of the shape maintaining member 40 is the same at each position, but may be different depending on the number and thickness of the linear conveyance members 30, the width dimension of the sheet-like member 22, and the like. For example, when the dimension along the parallel direction of the linear conveying members 30 changes before and after branching, the width dimension of the shape maintaining member 40 on the side where the dimension along the parallel direction of the linear conveying members 30 is large is considered to be larger than the width dimension of the shape maintaining member 40 on the side where the dimension along the parallel direction of the linear conveying members 30 is small. For example, when there are portions where the width of the sheet-like member 22 is different, the width of the shape maintaining member 40 is considered to be different depending on the width of the sheet-like member 22.

The shape maintaining member 40 is fixed with the sheet member 22. Here, in the one-side covering section 12, the shape maintaining member 40 is fixed together with the sheet member 22 at the side of the linear conveying member 30.

Therefore, in the wiring member 10, the wire-shaped transmission member 30 and the shape maintaining member 40 are fixed to the sheet-shaped member 22, respectively. Hereinafter, the linear transport member 30 and the shape maintaining member 40 may be collectively referred to as fixing

target members

30 and 40. In this case, the fixing method between the sheet member 22 and the

members

30 and 40 to be fixed is not particularly limited. The fixing method may be contact portion fixing, non-contact portion fixing, or both. Here, the contact portion fixation means that the sheet-like member 22 is fixed by being bonded to the portions that are in contact with the

fixation target members

30 and 40. The non-contact portion is fixed to a contact portion. For example, the fixing

members

30 and 40 and the sheet member 22 are held in a fixed state by pressing the fixing

members

30 and 40 toward the sheet member 22 with a suture, another sheet member 22, an adhesive tape, or the like, or by sandwiching the fixing

members

30 and 40 and the sheet member 22 with a suture, another sheet member 22, an adhesive tape, or the like in a state of surrounding the fixing

members

30 and 40 and the sheet member 22. Hereinafter, a case where the fixing

target members

30 and 40 and the sheet member 22 are fixed at the contact portions will be described. The descriptions of the contact portion fixation can be applied to the non-contact portion fixation as long as the non-applicable configuration is not adopted.

The contact portion may be fixed indirectly, directly, or in a different region. Here, the indirect fixation of the contact portion means that the

fixation target members

30 and 40 and the sheet member 22 are indirectly fixed by an intervening member such as an adhesive, a double-sided tape, or a surface fastener provided therebetween. The direct fixation of the contact portion means that the

fixation target members

30 and 40 and the sheet member 22 are directly bonded and fixed without using a separate adhesive or the like. For example, it is conceivable that the contact portion is directly fixed by melting a resin contained in at least one of the fixing

target members

30 and 40 and the sheet member 22 and then adhering and fixing the same. Hereinafter, a case will be described in which the fixing

target members

30 and 40 and the sheet member 22 are directly fixed at the contact portions. The description of the direct fixation of the contact portion can be applied to the indirect fixation of the contact portion as long as the direct fixation is not an inapplicable structure.

In forming such a state in which the contact portion is directly fixed, it is also considered that the resin is melted by, for example, heat, and that the resin is melted by a solvent. That is, the contact portion may be directly fixed by heat or by a solvent. Preferably, the contact portion is directly fixed by heat.

In this case, the method for forming the state in which the contact portion is directly fixed is not particularly limited, and various methods including known methods such as welding, fusing, and soldering may be used. For example, when the contact portion is directly fixed by heat by welding, various welding methods such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding can be used. When the contact portions are directly fixed by these methods, the

fixation target members

30 and 40 and the sheet member 22 are directly fixed by the contact portions by these methods. Specifically, for example, when the contact portions are directly fixed by ultrasonic welding, the

fixation target members

30 and 40 and the sheet-like member 22 are directly fixed by the contact portions of the ultrasonic welding. The portion where the contact portion by heat is directly fixed by welding (the fixed portion of the fixing

target members

30 and 40 and the sheet member 22) may be referred to as a welded portion, the fixed portion by ultrasonic welding may be referred to as an ultrasonic welded portion, and the fixed portion by heat and pressure welding may be referred to as a heat and pressure welded portion.

In the case of direct fixation of the contact portion, only the resin contained in the

fixation target members

30 and 40 may be melted, or only the resin contained in the sheet-like member 22 may be melted. In these cases, the molten resin may adhere to the other outer surface, forming a relatively sharp interface. In the case where the contact portion is directly fixed, both the resin contained in the fixing

target members

30 and 40 and the resin contained in the sheet-like member 22 may be melted. In this case, the resins of the two may sometimes be mixed together without forming a distinct interface. In particular, when the fixing

target members

30 and 40 and the sheet member 22 include easily meltable resins such as the same resin material, the resins of the two may be mixed together without forming a distinct interface.

For example, in the case of fixing the sheet-shaped member 22 and the

members

30 and 40 to be fixed by ultrasonic welding, it is conceivable to apply ultrasonic vibration by a horn while sandwiching the sheet-shaped member 22 and the

members

30 and 40 to be fixed by the horn and an anvil of an ultrasonic welding machine. As a result, the material of at least one of the sheet-like member 22 and the fixing

target members

30 and 40 is melted by the frictional heat generated at the interfaces between the sheet-like member 22 and the fixing

target members

30 and 40, and the sheet-like member 22 and the fixing

target members

30 and 40 are fixed.

The

fixation target members

30 and 40 to which the contact portions with the sheet-like member 22 are directly fixed preferably include the same material as the sheet-like member 22. In particular, it is preferable that the resin composition as the material of the members to be fixed 30 and 40 and the resin composition as the material of the sheet-like member 22 are mainly composed of the same resin.

When the linear transport member 30 and the shape maintaining member 40 are directly fixed to the sheet-like member 22 at the contact portion, the sheet-like member 22 may be formed of a different material or the same material or structure as the portion directly fixed to the linear transport member 30 at the contact portion and the portion directly fixed to the shape maintaining member 40 at the contact portion. In the case where the covering layer 34 of the linear transport member 30 and the shape maintaining member 40 are formed of different resins as main components, it is preferable that the portion of the sheet-like member 22 that is directly fixed to the contact portion with the linear transport member 30 is a material having better compatibility with the linear transport member 30 than with the shape maintaining member 40, and the portion of the sheet-like member 22 that is directly fixed to the contact portion with the shape maintaining member 40 is a material having better compatibility with the shape maintaining member 40 than with the linear transport member 30.

The fixing manner between the sheet member 22 and the linear transport member 30 and the fixing manner between the sheet member 22 and the shape maintaining member 40 may be the same or different. In this case, as a combination of different types of fixing methods, any of the fixing methods may be combined.

The shape maintaining member 40 is provided so that the wiring member 10 can be folded at the middle portion. An easy-to-fold portion 16 for achieving this folding is formed in the wiring member 10. The easy-to-fold portion 16 is a portion where folding of the wiring member 10 at the position of the easy-to-fold portion 16 is easier than folding of the wiring member 10 at the position that is not the easy-to-fold portion 16 and is provided with the shape maintaining member 40. Here, as the easy-folding portion 16, a first easy-folding portion 17 and a second easy-folding portion 18 are formed.

The first easily folded portion 17 is a portion where the shape maintaining member 40 is provided at intervals in the longitudinal direction of the wiring body 20 as described above. The wiring member 10 can be folded between the shape maintaining members 40 provided at intervals.

The second easy-to-fold portion 18 is a portion where the corrugated portion 42 is formed in the shape maintaining member 40. The corrugated portion 42 is formed such that the ridges 43a and the valleys 43b are continuous in the longitudinal direction of the wiring body 20. The hills 43a and valleys 43b are formed to extend in the width direction of the wiring body 20. The wiring member 10 can be folded at the portion covered with the corrugated portion 42. As the shape maintaining member 40 having the corrugated portion 42, for example, a member formed into a shape having the corrugated portion 42 by injection molding or the like can be used. Further, for example, a flat plate may be press-formed into a member having the shape of the corrugated portion 42.

However, it is not necessary to form both the first easy-to-fold portion 17 and the second easy-to-fold portion 18 as the easy-to-fold portion 16, and only the first easy-to-fold portion 17 or only the second easy-to-fold portion 18 may be formed as the easy-to-fold portion 16.

The portion where the easy-to-fold portion 16 is formed is not particularly limited, and may be set according to a folded shape, an assembly shape into a vehicle, or the like. Preferably, the easy-to-fold portion 16 is preferably formed at a portion that is bent in the front-rear direction when the wiring member is assembled to the vehicle. This makes it possible to easily bend the foldable portion in the front-rear direction when the foldable portion is assembled to the vehicle.

The wiring member 10 is folded using the easy-to-fold portion 16 so that the end side portion overlaps the middle side portion. At this time, the wiring member 10 can be folded so that the outward principal surface of the shape maintaining member 40 provided on the middle portion is exposed in a state where the end portion side portion is folded to be superimposed on the middle portion. That is, the end side portions can be folded to overlap only a part of the middle side portion. This enables the suction pad (vacuum pad) to be in contact with the middle portion of the exposed shape maintaining member 40. In addition, it is considered that, in a state where the wiring member 10 is folded, a middle side portion which is the lowermost side is a base portion, and a portion overlapping with the base portion is a branch portion.

In the example shown in fig. 1, each end side portion is folded only once. Therefore, the portion from the middle side portion to the end side portion is folded into a U shape. However, the end side portion may be folded multiple times. When the end portion side portion is folded a plurality of times, the end portion side portion may be folded in a spiral shape so as to be positioned inside, or the end portion side portion may be folded in a corrugated shape so as to be positioned outside.

In the case where the adsorption pad is in contact with the shape maintaining member 40, the portion is preferably formed to be highly airtight. From this viewpoint, the shape maintaining member 40 is preferably a solid material or a separate foamed material.

< action >

Fig. 6 is an explanatory diagram showing a state of the feeding wiring member 10.

Since the shape maintaining member 40 is sheet-shaped, the suction pad P abuts against the outward main surface of the shape maintaining member 40, and the shape maintaining member 40 can be held by the suction pad P. Therefore, the wiring member 10 can be lifted and transported by the robot R or the like provided with the suction pad P. The portion contacted by the suction pad P is, for example, a region a indicated by a two-dot chain line in fig. 1.

When the wiring member 10 is lifted at a predetermined portion, more specifically, when a portion of the wiring member where the shape maintaining member 40 is provided on the end portion side of the portion in contact with the suction pad P is lifted so as to extend in a cantilever shape, the cantilever-shaped portion does not droop due to the rigidity of the shape maintaining member 40 or sags in a bow shape even if it droops. As shown in fig. 6, the bow-shaped sagging manner is a sagging manner as follows: when the wiring member 10 in a suspended state with a predetermined portion lifted is placed on a table S wider than the wiring member 10, the suspended portion does not bend inward on the table S and overlap with other portions thereon, that is, the suspended portion spreads outward on the table S. Thus, after the wiring member 10 is conveyed by the robot R provided with the suction pad P, the overlapping of the end portions does not need to be repaired, and therefore, the assembly workability can be improved.

In the example shown in fig. 1, the suction pad P is in contact with the wiring member 10 at two locations, but the location where the suction pad P is in contact is not limited thereto. The contact portion of the adsorption pad P may be one or three or more. However, it is preferable that the wiring member 10 can be lifted so as not to largely hang down at as few portions as possible. For example, the wiring member 10 may be lifted so as not to largely hang down in consideration of the fact that the suction pads P contact portions smaller in number than the end portions.

Fig. 7 is a plan view showing a modification of the folding method of the wiring member 10. In fig. 7, the left-side end portion shows a state before folding, and the right-side end portion shows a state after folding. The right-side terminal portion is the same as the left-side terminal portion when deployed.

The end side portion has been folded so that a line orthogonal to the longitudinal direction of the linear transport member 30 is a fold, but this is not an essential configuration. As in the example shown in fig. 7, the end side portion may be folded so that a line intersecting the longitudinal direction of the linear transport member 30 at an angle other than perpendicular is a fold. This allows the portion of the shape maintaining member 40 exposed to the main surface facing outward to be changed, and a desired position to be easily exposed. At this time, the portion contacted by the suction pad P is, for example, a region a indicated by a two-dot chain line in fig. 7.

For example, as shown in fig. 7, in the first easily foldable portion 17A, the end edge portions of the shape maintaining member 40 facing each other with a gap therebetween extend obliquely with respect to the linear transport member 30, so that the end side portions can be folded so as to form folds with lines intersecting the longitudinal direction of the linear transport member 30 at angles other than orthogonal. In addition, for example, as shown in fig. 7, in the second easy-to-fold portion 18A, the ridge 43a and the valley 43b of the corrugated portion 42 are formed to extend obliquely with respect to the linear transport member 30, so that the end portion side portion can be folded so as to form a fold line with a line intersecting the longitudinal direction of the linear transport member 30 at an angle other than the angle orthogonal thereto. In addition, for example, since the interval of the shape maintaining members 40 is wide, the end side portion can be folded so that a line intersecting the longitudinal direction of the linear transport member 30 at an angle other than the orthogonal angle is a fold.

According to the wiring member 10 configured as described above, since the shape maintaining member 40 having higher rigidity than the sheet-like member 22 covers the wiring body 20, the wiring member 10 is less likely to sag. In particular, when the middle portion of the wiring member 10 is lifted, the end portion side portion of the wiring member 10 can be suppressed from largely drooping. This can improve the assembling property of the wiring member 10.

Further, since the shape maintaining member 40 has the one-side covering portion 12 covering the linear transport member 30 only from the side opposite to the sheet member 22, the number of components can be reduced as compared with the case where the shape maintaining member 40 covers both sides.

In addition, in the one-side covering section 12, since the shape maintaining member 40 and the sheet member 22 are directly fixed at the contact portion on the side of the linear transport member 30, a fixing member that remains on the wiring member 10 and fixes the shape maintaining member 40 and the sheet member 22 can be omitted.

In addition, the shape maintaining member 40 is provided so that the wiring member 10 can be folded at the middle portion. The wiring member 10 is folded at the intermediate portion, so that the form during conveyance can be made compact. The wiring member 10 is considered to be a large wiring member 10 that is bulky if left as it is, for example, and therefore the transportation cost from the manufacturing plant to the assembly plant becomes high.

Further, since the shape maintaining members 40 are provided with a space in the longitudinal direction of the wiring body 20 and the wiring member 10 can be folded between the shape maintaining members 40 provided with a space, the wiring member 10 can be folded with a simple configuration.

Further, since the shape maintaining member 40 includes the corrugated portion 42 formed such that the ridges 43a and the valleys 43b are continuous in the longitudinal direction of the wiring body 20, the wiring body 20 can be covered with the shape maintaining member 40 such that the wiring body 10 can be folded at the portion covered with the corrugated portion 42.

In addition, since the wiring member 10 can be folded so that the end portion side portions are folded so as to be superimposed on the middle portion side, the outward principal surface of the shape maintaining member 40 provided on the middle portion side is exposed, and therefore the suction pad P can be brought into contact with the middle portion side of the exposed shape maintaining member 40. This makes it easy to transport the wiring member 10 in the folded state by the robot R or the like.

Further, since a plurality of linear transmission members 30 are provided in parallel, the wiring member 10 can be formed flat. This facilitates two-dimensional processing of the wiring member 10. In addition, it is easy to secure a plane for bringing the suction pad P into contact with the shape maintaining member 40. In addition, when the wiring member is assembled, the contact area with the mating member can be increased, and thus the wiring member can be easily fixed with an adhesive, a tape, or the like.

[ second embodiment ]

A wiring member according to a second embodiment will be described. Fig. 8 is a plan view showing the wiring member 110 according to the second embodiment. Fig. 9 is a partial sectional view taken along line IX-IX of fig. 8. In the description of the present embodiment, the same components as those described so far are denoted by the same reference numerals, and the description thereof is omitted.

The wiring member 110 according to the second embodiment is different from the wiring member 10 according to the first embodiment in that the shape maintaining member 140 is provided continuously along the longitudinal direction of the wiring body 120 so as to maintain the shape of the entire wiring body 120.

More specifically, the shape maintaining member 140 is connected as a whole, and the first easy-to-fold portion 17 is not provided in the wiring member 110. In addition, the corrugated portion as the second easy-to-fold portion 18 is not formed in the shape maintaining member 140. Thus, the wiring member 110 does not have the easy-to-fold portion 16, and the shape maintaining member 140 can maintain the shape of the entire wiring body 120.

Here, when the shape of the entire wiring body 120 is maintained, the terminal portion may be excluded or included. More specifically, here, the distal end portion of the linear transmission member 130 (in the example shown in fig. 8, the connector C) is provided outside the shape maintaining member 140. In this case, the shape retaining member 140 can maintain the shape of the entire wiring body 120 except for the distal end portion. In addition, even in this case, if the size of the tip portion extending from the shape maintaining member 140 is small, the shape of the tip portion can be substantially maintained. In contrast, the distal end portion of the linear transport member 130 may be provided on the shape maintaining member 140. In this case, the shape of the entire wiring body 120 including the terminal portion can be maintained.

When the shape maintaining members 140 are continuously provided along the longitudinal direction of the wiring body 120 so as to maintain the shape of the entire wiring body 120 as described above, the rigidity of the entire wiring member 140 can be increased. The wiring member 110 is considered to be, for example, a small wiring member 110 that is easily transported from a manufacturing factory to an assembly factory even if it is not folded. At this time, the portion where the suction pad P contacts is considered to be, for example, a region a indicated by a two-dot chain line in fig. 8.

The wiring member 110 according to the second embodiment is also different from the wiring member 10 according to the first embodiment in that it has both side covering portions 14.

The both-side covering portions 14 are portions of the shape maintaining member 140 covering both sides in the front-rear direction of the wiring body 20. In the example shown in fig. 8, a case where the portion of the wiring member 110 where the shape maintaining member 140 is provided is constituted only by the both-side covering portions 14 will be described. The both side covering portions 14 are constituted by two shape maintaining members 140. Hereinafter, when it is necessary to distinguish between the two shape maintaining members 140, the shape maintaining member positioned on the side of the linear transport member 130 may be referred to as a shape maintaining member 140a, and the shape maintaining member positioned on the opposite side (the sheet member 122 side) may be referred to as a shape maintaining member 140 b.

In the both-side covering portions 14, the two shape maintaining members 140 are fixed in a state of sandwiching the wiring body 120. At this time, in the example shown in fig. 8, the shape maintaining members 140 are directly fixed to each other. The fixing method of the shape maintaining members 140 can be applied to any of the fixing methods of the sheet-like member 122 and the fixing object thereof described in the first embodiment, but it is preferable that the contact portion is fixed, and it is more preferable that the contact portion is directly fixed.

In the example shown in fig. 8, the sheet member 122 is not directly fixed to one shape maintaining member 140. In the wiring body 120, a portion where the sheet-like member 122 overlaps the linear transmission member 130 is sandwiched and fixed by two shape maintaining members 140. In the example shown in fig. 8, the wiring body 120 is not formed such that only the sheet member 122 of the sheet member 122 and the linear transmission member 130 is sandwiched and fixed by the two shape maintaining members 140 on the side of the linear transmission member 130. Of course, in the wiring body 120, the sheet-like member 122 and only the sheet-like member 122 of the linear transmission members 130 may be sandwiched and fixed by the two shape maintaining members 140 on the side of the linear transmission members 130.

Of course, the sheet member 122 may be directly fixed to one shape maintaining member 140. In this case, the sheet-like member 122 and the shape maintaining member 140b may be directly fixed to the rear side of the linear transport member 130, or the sheet-like member 122 and the shape maintaining member 140a, the shape maintaining member 140b, or both may be directly fixed to the side of the linear transport member 130. At this time, it is also considered that the two shape maintaining members 140 are not directly fixed to each other, but the two shape maintaining members 140 are directly fixed to the sheet member 122, respectively.

By providing such both side cover portions 14, the rigidity of the wiring member 110 can be further improved. Alternatively, since necessary rigidity can be obtained by the shape maintaining members 140 on both sides, a member having low rigidity can be used as one shape maintaining member 140.

[ modified examples ]

The case where a base material formed in a flat sheet shape is used as the

shape maintaining member

40 or 140 has been described so far, but this is not an essential configuration. There may be a case where the shape maintaining member is formed three-dimensionally.

The shape maintaining member 240 shown in fig. 10 includes a planar forming portion 44 and a cubic forming portion 46. Here, the shape maintaining member 240 constituting a part of the one-side covering portion 12 is three-dimensionally molded.

The planar forming portion 44 is a portion shaped like a plane. For example, the planar forming portion 44 is a portion covering the linear transmission member 30.

The three-dimensional forming portion 46 is a portion formed to rise from a part of the planar forming portion 44 in the width direction to the front and back direction of the planar forming portion 44 and to extend in the longitudinal direction. Here, as the three-dimensional forming portion 46, side wall portions 47 rising up on both sides of the planar forming portion 44 and a flange portion 48 spreading laterally from one end of the side wall portion 47 are formed. Therefore, the shape maintaining member 240 is formed in a groove shape having the flange portion 48. The linear transmission member 30 is accommodated in a portion of the groove surrounded by the planar forming portion 44 and the side wall portion 47, and the flange portion 48 is fixed to the sheet member 22.

Here, in the one continuous shape maintaining member 240, the one three-dimensional forming portion 46 is continuous in the longitudinal direction. However, the shape of the three-dimensional forming portion 46 may be different in the longitudinal direction in one continuous shape maintaining member 240.

It is considered that the shape maintaining member 240 is formed by, for example, vacuum-forming a base material formed into a sheet shape into a three-dimensional shape. Further, for example, it is also conceivable that the shape maintaining member 240 is molded into a three-dimensional shape from the beginning by extrusion molding or the like.

The shape of the three-dimensional forming portion 46 is not limited to the above shape. For example, a rib may be provided as the three-dimensional forming portion 46 on the outer surface side of the planar forming portion 44. Only one rib may be provided, or a plurality of ribs may be provided.

As the shape maintaining member constituting a part of the both side covering portions 14, a three-dimensionally molded shape maintaining member 240 may be used. At this time, in the both-side covering portions 14, the three-dimensionally formed shape maintaining member 240 may be used only for the shape maintaining member covering the linear transport member 30 side out of the two shape maintaining members, may be used only for the shape maintaining member covering the sheet-like member 22 side, or may be used for both. When the two shape maintaining members forming the both side covering portions 14 are formed by using the three-dimensionally formed shape maintaining member 240, the two members may be formed in the same shape or in different shapes.

By providing such a three-dimensional forming portion 46, the rigidity of the shape maintaining member 240 can be further improved. In particular, the rigidity of the shape maintaining member 240 in the longitudinal direction can be further improved. At this time, if the shape maintaining member 240 is three-dimensionally shaped to form the groove portion 50 capable of accommodating the linear transport member 30, it is possible to suppress a force applied to the linear transport member 30 when the shape maintaining member 240 sandwiches the linear transport member 30. The same applies to the case where the three-dimensional forming portion 46 is provided in the shape maintaining member 240 constituting the both side covering portions 14.

In the example shown in fig. 2 and 9, the width-direction end portions of the

shape maintaining members

40 and 140 are deformed so as to be bent with respect to the middle portion. For example, when the sheet-

like members

22 and 122 and the

shape maintaining members

40 and 140 or the shape maintaining members 140 are fixed to each other on the sides of the

linear transmission members

30 and 130, the

shape maintaining members

40 and 140 may be deformed in this manner. In this case, when the deformation is a three-dimensional deformation in which the rigidity is improved as compared with a case where the

shape maintaining members

40 and 140 are held as flat base materials, and the deformed state is maintained even when the fixed state is released, the

shape maintaining members

40 and 140 deformed in this manner can be understood as one of the shape maintaining members 240 including the planar formed portion 44 and the three-dimensional formed portion 46.

In addition, the case where the wiring member 10 having the easy-folding portion 16 has only the one-side covering portion 12 has been described so far, but this is not a necessary configuration. Also, the case where the wiring member 110 without the easy-folding portion 16 has only the both-side covering portions 14 has been described, but this is not a necessary configuration. For example, the both-side covering portions 14 may be applied to the wiring member 10 having the easy-folding portion 16, and the one-side covering portion 12 may be applied to the wiring member 110 not having the easy-folding portion 16. In the case where the both-side covering portions 14 are applied to the wiring member 10 having the easy-to-fold portion 16, if the both-side covering portions 14 are present in the distal end side portion, the shape maintaining member is also exposed on the outer surface of the distal end side portion in the folded state. Therefore, the distal end portion can be developed by bringing the suction pad P into contact with this portion.

In addition, the case where one wiring member 10 has only the one-side covering portion 12 or only the both-side covering portions 14 has been described so far, but this is not a necessary configuration. One wiring member 10 may also have both the one-side covering portion 12 and the both-side covering portions 14. In this case, the one-side covering portion 12 and the both-side covering portions 14 are considered to be present at different positions in the longitudinal direction of the wiring body 20.

The shape maintaining member 40 may cover at least a part of at least one of the front surface and the back surface of the wiring body 20 to maintain the shape of the wiring body 20. In the wiring body 20, the side where the linear transmission member 30 is located with respect to the sheet member 22 is a front surface, and the opposite side is a back surface. The one-side covering portion 12 is a portion where the shape maintaining member 40 covers only the surface of the wiring body 20. The both side covering portions 14 are portions where the shape maintaining member 40 covers both the front surface and the back surface of the wiring body 20. In the case where the shape maintaining member 40 covers only one surface of the wire body 20, the shape maintaining member 40 may cover only the back surface of the front surface and the back surface of the wire body 20. When the shape maintaining member 40 covers only the back surface of the wiring body 20, the shape maintaining member 40 may be fixed to the back surface of the sheet-like member 22 over the entire surface thereof, or may be fixed to only a portion of both sides thereof. Further, the shape maintaining member 40 covering the front surface of the wiring body 20 and the shape maintaining member 40 covering the back surface may be provided in different regions along the longitudinal direction of the linear transport member 30.

In addition, although the case where the linear transmission member 30 and the

shape maintaining members

40, 140, and 240 are not directly fixed has been described so far, this is not an essential configuration. The linear transmission member 30 and the

shape maintaining members

40, 140, and 240 may be directly fixed. The fixing method in this case is not particularly limited, and any of the fixing methods between the sheet-like member 22 and the object to be fixed described in the first embodiment may be used. For example, it is conceivable that the linear transport member 30 and the shape maintaining member 40 are directly fixed at the contact portion.

The configurations described in the embodiments and the modifications may be appropriately combined unless contradicted by each other.

As described above, the present disclosure has been described in detail, but the above description is illustrative in all aspects, and the present disclosure is not limited thereto. It is understood that numerous variations not illustrated may be contemplated without departing from the scope of the present disclosure.
